Device presetting

You can preset the thermostat on the first power-on or immediately after a factory

reset. The thermostat will require the selection of a preset to pre-configure settings

depending on what the thermostat is directly controlling, which allows the

thermostat to function correctly for the intended use case. Preset selection is a

manual process and all preset uses a PI control algorithm which provides highly

stable results.

You can choose one preset configuration:

Preset Configuration Control type / Set

point range Cycle time* (min)

P1 Heat Pump/Oil Boiler

Room Control

4°C ~ 30°C

P2 Hydronic Radiator/Gas Boiler 10

P3 Hydronic Underfloor 10

P4 Electrical Radiator 10

P5 Electrical Underfloor (Without

floor limits) 10

P6 Electrical Underfloor (With floor

limits) 10

P7 Hydronic Underfloor Floor Control

*Cycle time: This setting determines the length of each on/off cycle of the output

relay. The percentage of time within that cycle time that the relay is on is varied

based on demand. A longer cycle time may be more appropriate for slow heating

surfaces, such as a concrete floor. A short cycle time is more appropriate for faster

heating surfaces, such as an electric panel heater.

Initial preset configuration (by default)

When the thermostat is first powered on or immediately after a factory reset, by

default “P5” flashes on the matrix LED’s if there is no external sensor connected,

or “P8” if there is any external sensor connected.

Modifying the preset value

To modify the preset from default value, simultaneously press "O" and "+" for 10 s

to enter advanced settings menu. Then press +button on the thermostat, it

increases the preset value by 1 and when –button is pressed, it decreases the

preset value by 1.

For example, when +button is pressed, preset P1 becomes P2, continue to press

the +button, and the preset changes to P3, P4...P9.

Similarly, when –button is pressed, preset P9 changes to P8, continue to press

the –button, preset changes to P7, P6...P1.

8 DUG_ZB Thermostat 16 A_ELKO-00

Smart ZB Thermostat 16 A

Confirming the preset

Select the preset that meets your needs using the +/- buttons, and then hold the O

for > 1 s to confirm the selection.

For example, P1 is confirmed.

> 1 s

• Cycle Time : 20 mins
